I just got a GC Freeloader for cheap (read: FREE!), and I have no idea what the best titles to go for would be - NONE. Help a man out. I like all kinds of games, but, if it helps, I am currently re-addicted to the Kagero/Deception series, a huge Splinter Cell fan, and enjoy all things FPS, for the most part. I like a good party game, too. The only titles I have for GC as of this post are Metroid Prine 1 & 2, as well as Resident Evil 0 & 1 (I primarily got the GC for Gameboy/GBC/GBA carts). Fire away!
Nintendo Puzzle Collection is great, mainly because of Panel de Pon (Tetris Attack), but Dr. Mario is nice too. Always thought Yoshi's Cookie kinda sucked. It also comes with a GC-GBA cable, if you really want one.

Nice! I've read about all these, but, I understand your opinions more than other forums' members. Keep 'em coming.
